C2 Deck Fix Premium Woodscrews – The Ultimate Solution for Joiners & DIYers

When working on outdoor decking, fencing, and landscaping projects, using the right screws is not just important—it’s essential. The choice of fixings determines how well a structure holds up over time, especially when exposed to the harsh UK weather. At Next Day Fixings, we supply a wide range of high-quality fixings designed for joiners, tradespeople, and DIYers who want to get the job done right.


One of the best options for decking and outdoor structures is the C2 Deck Fix Premium Woodscrews by TIMco. These screws are specifically engineered to offer exceptional holding power, anti-corrosion properties, and effortless installation, making them the perfect choice for professionals and hobbyists alike. In this guide, we’ll take a deep dive into why C2 Deck Fix Premium Woodscrews stand out from the competition and why they should be your go-to option for outdoor projects.


What Are C2 Deck Fix Premium Woodscrews?

C2 Deck Fix Premium Woodscrews are high-performance decking screws designed to withstand harsh outdoor conditions while delivering superior strength and durability. Manufactured by TIMco, a brand known for its innovative approach to fixings, these screws incorporate twin-cut technology for a secure grip, reduced timber splitting, and smooth countersinking.


Unlike standard screws, C2 Deck Fix screws are coated with a multi-layer corrosion-resistant plating, which has been tested to withstand 1,000 hours of salt spray exposure. This level of protection ensures they remain rust-free, even when exposed to rain, moisture, and temperature fluctuations over long periods. If you’re working on a project that needs long-term stability, these screws are a game-changer.


Why Choose C2 Deck Fix Premium Woodscrews?

A common mistake made by DIYers and even some professionals is using standard woodscrews for decking and outdoor applications. However, these screws often rust quickly, snap under pressure, and fail to hold the timber securely over time. To illustrate why C2 Deck Fix screws are the superior choice, we’ve put together a direct comparison:
